CLAMP FOR WEEDER ATTACHMENTS Filed May 9, 1953 /9 WW 1! i My Quinn Mo? Patented Dec. 26, 1933 7 UNITED STATES PATENT OFFICE horizontal position or in a position parallel with the edges of the cultivator blades.

Another object of this invention is to provide a clamp of this kind which has been particularly designed for holding the cultivator attachment or weeder disclosed in the patent of Lucian Morrison, et a1., 1,682,182, issued August 28, 1928. This clamp, with covered sockets, has the advantage of holding the attachment in adjustment when set,

and will remain in place until adjustment is changed. r

The above and various other objects and advantages of this invention will in part be described and in part be understood from the following detailed description of the present preferred embodiment, the same being illustrated in the accompanying drawing, wherein:-

Figure 1 is a detail rear elevation of a pair of plates constructed according to the embodiment of this invention, showing the plates in mounted position on a cultivator.

Figure 2 is an enlarged sectional view taken on the line 2-2 of Figure 1.

Figure 3 is a perspective view of one of the clamping plates.

Referring to the drawing wherein like numerals of reference designate corresponding parts throughout the several views, the'numeral 10 designates generally the supporting shank for a cultivator blade 11. This cultivator blade 11 is secured tothe foot portion 12 of the shank 10 by means of a pair of spaced bolts 13 or the like.

In order to hold the weeder attachment 14,

which is disclosed in the patent of Lucian Morrison, et a1., 1,682,182, which attachment comprises an elongated bar 15 having a curved inner end portion 16 and a loop 17, I have provided a clamping means in the form of a plate 18 provided intermediate the ends thereof with a curved slot or recess 18. This recess 19 opens on the inner face:

of the plate 18 and on each side edge of the plate. The curved portion 16 of the attachment 14 is adapted to bear against the lower surface of the foot 12 and to be held in adjusted position relative to this foot 12 by means of theplate 18. This plate 18 is provided adjacent each end thereof with elongated slots 20, which are adapted to loosely receive the bolts 13, and these plates 5 18 may be adjusted relative to the longitudinal axis of the shank 10 in a manner to permit'the V positioning of pairs of these attachments 14 in the desired position one relative to the other.

As shown in the Patent, 1,682,182, these attachthe attachments to the supporting means.

ments 14 are positionedwith the straight portions 15 thereof in crossed relation and in order to have'these straight portionsv 15 intersect or cross each other at the desired point, the plate 18 is made adjustable by means of the elongated slots 20.

By using a clamp of this kind, it is possible to use the weeder attachment hereinbefore described without the necessity of providing additional supporting means in the form of depending shanks or the like, thereby eliminating the cost of these additional shanks with the, means for securing The plate 18 is preferably adapted to be positioned on the lower side of the foot 12 so that in the movement of the blade 11 through the ground, the'plate 18 will not become worn. The groove or socket 19 is not only curved longitudinally but is positioned on anangle to the longitudinal axis of the plate 18 so as to properly position pairs of these weeder attachments 14 in crossed relation.

In the use of the device in combination with theweeder attachment hereinbefore set forth, the nuts for the bolts 13 may be loosened and the plate 18 slipped over these bolts 13 with the curved end portion 16 seating in the segmental socket 19. The nuts for the bolts 13' may then be tightened to the desired degree so as to mount the attachments 14in a desired position one relative to the other.

It is, of course, understood that various changes and modifications may be made in the details of construction and design of the above specifically described embodiment of this invention without departing from the spirit thereof, such changes and modifications being restricted only by the scope of the following claim.

What is claimed is:

In combination with a cultivator foot piece having a plane surface on one side thereof and a weeder attachment having a curved inner end portion, a clamp for holding said curved inner end portion against the plane surface of said foot piece, said clamp comprising an elongated plate having a longitudinally curved socket therein opening through one face of the plate and
